Providing contextual information will be the cornerstone of vehicular services in next-generation vehicles, thanks to the integration of telematics and vehicular communications. In intelligent transportation systems, this capability will have a key role for transmitting traffic incidents. Although many solutions allow for sharing information between vehicles and between the vehicle and the infrastructure, none presents a valid general communication architecture for the collection, management, and provision of context-aware information on traffic and current location. The proposed integrated vehicular system uses an integrated vehicle-to-vehicle and vehicle-to-infrastructure communication paradigm enriched with an information management system. The infrastructure manages safety hazards detected from vehicles and relevant information to send the user, and adapts these to the vehicle's context and driver's preferences.
